I have a Ruger RH and a Taursus RB in .454. I have never shot anything but 300 grn. bullets at 1,500 fps. from eather. The Ruger has far more recoil, and I think because of that is not nearly as accurate. I shoot both with iron sights. I did get my Super RH used, like new, at a gun show, for $400 in the box with rings. For $568 I could get a new one around here, Ohio. The RH is a well made gun and with the .45 Colt ammo would be very easy to shoot. The RB is still a 2 hand gun as it weights so much you can`t hold it with one hand. I`ve heard about some problems with Taursus customer service and quality lately, but not Ruger, but have personally ahd any trouble with eather.
